I have a 134a conversion label on my car dated 10/11. The AC is cooling but the low pressure switch is cycling. I put 2 small cans (1 lb I think) using a cheap consumer grade gauge and only got to about 12 psi. The 2 cans did raise it from about 8 psi.

For some reason I'm EXTREMELY PARANOID about my drier going out and flooding my system with junk! I plan on having an AC shop replace the drier and pressure switch in the near future.

So, do I have reason to worry? Should I put another can of 134a in it or just wait until I have pros do it?

Thanks.
